Risk Categories
Content Detection Domains

Nine risk categories.
Every linguistic surface.

Exhaustive coverage across core linguistic risk categories using hyper-specific detection vectors. Configure thresholds independently per category and per scenario.

Sexual
Detect explicit material and suggestive narratives (soft porn) with multi-level severity scoring for granular moderation policies.
TIER · CRITICAL
Hate Speech
Recognize slurs, defamation, and targeted attacks based on protected characteristics or personal identity across diverse contexts.
TIER · HIGH
Prohibited Goods
Flag the promotion of illicit weapons, narcotics, gambling, and counterfeit services or fraudulent behaviors.
TIER · CRITICAL
Child Safety
Prevent grooming, exploitation, and exposure to age-inappropriate content to ensure a secure environment for minors.
TIER · CRITICAL
Spam
Detect and mitigate repetitive content, gibberish, and low-effort posts to foster authentic interactions.
TIER · MODERATE
PII Protection
Automatically detect and redact unauthorized sharing of personal data — IDs, bank details, phone numbers, private addresses.
COMPLIANCE
Illicit Advertising
Block unauthorized promotions and contact-harvesting attempts — social IDs, phone numbers, QR codes embedded in text.
TIER · HIGH
AI Safety
Hardened defense against LLM manipulation — prompt injection, jailbreaking, and deceptive role-play attacks.
LLM HARDENING
Symbolic & Emoji
Decipher the hidden intent behind complex emojis, character-based symbols, and evasive text variations.
SEMANTIC DECODE
Core Engine

Built for the language
of evasion.

Modern text risks aren't in keywords. They're in homophones, leetspeak, zero-width unicode, emoji combinations, and adversarial prompts. Our engine is designed for exactly that fight.

ANTI-EVASION FSA

Catching the uncatchable. By design.

Leveraging FSA (Finite State Automaton) algorithms, we identify complex text variants — homophones, character substitutions, pinyin, zero-width unicode — designed to bypass traditional rules. Our defense is positioned at the very front of the risk cycle, neutralizing evasion attempts before they escalate.

  • Unicode normalization catches zero-width and look-alike attacks
  • Phonetic matching handles homophones and pinyin substitution
  • FSA matching scales to millions of evasion patterns at low latency

99%+ ACCURACY · NLP STACK

FastText + HMM + CRF + Word2Vec. Fused.

Our engine integrates and innovates upon a diverse stack of cutting-edge NLP technologies: FastText, HMM, CRF, and Word2Vec. By fusing multiple models, we deliver a market-leading detection accuracy of 99%+, ensuring your platform remains clean without sacrificing user experience.

  • FastText for fast multilingual classification at scale
  • CRF for entity extraction (contact info, addresses, IDs)
  • Word2Vec embeddings for semantic similarity to known risks
  • HMM for sequential pattern recognition across long messages

AI SAFETY · LLM HARDENING

Hardened defense for the LLM era.

Generative AI platforms face a new class of risks. Our text engine includes a dedicated AI Safety layer — purpose-built to detect prompt injection, jailbreaking, role-play exploits, and deceptive instruction-following attacks that bypass standard moderation. Critical for chatbots, AI companions, and AIGC platforms.

  • Detection runs on both user input and LLM output
  • Pattern library updated continuously from real-world attacks
  • Context-aware — distinguishes legitimate role-play from exploits
